Anti-overturning structure additionally arranged for existing single-pier bridge
The invention discloses an anti-overturning structure additionally arranged for the existing single-pier bridge, which comprises a main beam, a single pier used for supporting the main beam, small bent caps arranged on the two sides of the single pier and check block bodies arranged at the outer ends of the two sides of the upper portions of the small bent caps, and steel springs connected with the check block bodies are arranged between the check block bodies and the side wall of the main beam. An anti-overturning support and an NV rubber mudguard are arranged between the small bent cap and the main beam, and the two ends of the anti-overturning support are connected with the top of the small bent cap and the bottom of the main beam respectively; the bottom of the NV rubber mudguard is connected with the top of the small bent cap in an anchored mode. By reducing the overturning moment of the bridge in the transverse direction and the energy absorption and buffering effects of the NV rubber mudguard, the anti-overturning force of the bridge is additionally provided through the elastic force of the steel spring, so that the anti-overturning capacity of the bridge is enhanced, the stress condition of the bridge is improved, and potential safety hazards of an existing bridge are eliminated.
本发明公开了一种为既有独柱墩桥梁增设的抗倾覆结构，包括主梁、用于支撑主梁的独柱墩、设置于独柱墩两侧的小盖梁以及设置于所述小盖梁上部两侧外端的挡块块体，所述挡块块体与所述主梁的侧壁之间设有与之连接的钢弹簧；所述小盖梁与所述主梁之间设有抗倾覆支座和NV橡胶护舷，所述抗倾覆支座的两端分别与所述小盖梁的顶部、主梁的底部相连；所述NV橡胶护舷的底部与所述小盖梁的顶部锚固连接。本发明通过减小桥梁横桥向的倾覆力矩，NV橡胶护舷吸能缓冲的作用，同时利用钢弹簧的弹力额外提供一个桥梁的抗倾覆力，以达到增强桥梁抗倾覆的能力，改善了桥梁的受力状况，消除现有桥梁的安全隐患。
